Used in organic synthesis as an intermediate for pharmaceuticals and bioactive compounds. Serves as a building block in the preparation of indole-based derivatives with potential medicinal properties, including antimicrobial, anti-inflammatory, anticancer, and central nervous system agents. Also applied in the development of fluorescent dyes and sensors due to its conjugated structure that supports light absorption and emission. Commonly utilized in research settings for structure-activity relationship studies in drug discovery and creative chemistry to develop new complex structures.
